IMPROVEMENT IN WSH- BOILER ATTACHMENTS.

Specification forming part of Letters Patent No. lS h, dated December 24, 1872.

To all whom it may concern:

Be it known that I, ANNA ScHLoEssER, of

Des Moines, in the county of Polk and State of Iowa, have invented a Device for Washing iu a Boiler, of which the following is a speciication:

turned, rubbed, and cleansed. It consists in a device adapted to hold a quantity of clothing, and to lift in and out of a boiler, and -so formed as to cause the steam to lift on one side of the clothing while a volume of water is made to pour on and press down the opposite side in such a manner that the co-operative forces, cause the mass of clothing to revolve while boiling, and to be alternately subjected to the action of steam and a current of boiling water.

My drawing is a perspective View of a halfsection of my device, and illustrates the manner of its construction and operation.

a a represent the base or bottom. It may be formed complete from one piece of sheet metal, 0r may be composed by a combination of the different parts of my device. It may be entirely dat or may be depressed in the center and sides. b is arim turned downward. This or its equivalent is required to keep my device elevated an inch or more above the bottom of the boiler into which it is placed. A is a plate, attached on the side of the bottom piece in any suitable manner. It extends the entire length of the bottom a, and up high enough to reach near the top of the boiler. It may extend below to form a rest equivalent to the rim b on the opposite side. The top edge is curved inward and downward over a parallel plate. B is a plate inside of the plate A. It is joined to the bottom a at its lower edge, and extends upward into the curved top of the plate A. The ends of the plates are joined and closed in any suitable manner. The outside plate A may curve in- Ward to conform with the round ends of a boiler and to meet the inner plate B; or the plates may be of equal length, and pieces may be tted between them to close the ends. The

space between the two plates at their tops is about one inch. At the bottom the inner plate B curves away from the outside plate A in order to form a circular bottom to aid in revolving the clothing. 1 2 3 4 represent a series of metal straps with wired edges, in the form of ribs, attached to the bottom a, and connected at their tops in such a manner as to form a skeleton side for one side of my device. A series of perforations in the bottom a, on the outside of the ribs l 2 3 4, allows a free upward escape for the steam generated below. The skeleton side is designed to allow the rising current of steam to come in contact with the clothing and to lift them. The opposite and closed side formed by the plates A and B is open or perforated below, and allows a volume of water to rise between the plates.

The curved top of the outside plate A turns the volume of water down upon the clothing. The combined action of the steam lifting on the one side and the water pressing down ou the other side moves and revolves the clothing. The circular line of motion of the water, steam, and clothing is indicated by the arrows. c c represent handles, which may be made and attached in any suitable manner. My device may be made of tin-plate or any other suita- .ble non-corrosive material, and may vary in size and shape to t boilers of various forms and dimensions.

To operate my device, place it in a boiler about half full of soap-suds, and then put the boiler over the fire. Soak the clothing in water, and then place the articles lengthwise in the washing device. Do not pack them in, but lay them in loosely. In this manner it can be lled with garments, and two dozen of pieces can be washed as quickly as one piece, if the device is large enough to hold them without packing. Cover the boiler, and let the water boil until the articles are clean. The waterconductor A B acts as a condenser. By con ducting the water away from the heat, and cooling it in the upper part of the boiler, it draws the current of steam from the opposite and skeleton side, and condenses it and carM ries it along in its return to the bottom. The

currents of water and steam thus united on l one side press, move, and revolve the mass of clothing by force of gravity. When the cooled water reaches the bottom it again becomes heated, and presses toward the open skeleton side until its force is again united with the upward current of steam on the skeleton side.V A continuous circulation is thus produced. The water is not inclined, and does not rise sufficiently high to overflow the boiler. The clothes are alternately in steam and water, and kept moving so that the fabrics turn, rub, and press each other. Every portion is thus automatically manipulated and washed. When clean the device and its contents can be lifted and drained from the water in the boiler, and emptied into the rinsing-tub.

Glaimz I claim as my inventiond A Washingv device, to place in a boiler, hav ing a closed bottom, a a, water conductor and condenser A B on the one side, and a skeleton frame 1 2 3 4 on the opposite side, substantially as described, and for the purposes specified.
